In our 15 years serving Daly City, we've seen this problem again and again: homeowners don't know what type of garage door springs they have until one breaks. Torsion and extension springs look nothing alike, work nothing alike, and fail in completely different ways. Knowing which one you've got could save you time, money, and a lot of headache when something goes wrong.
Your garage door weighs between 300 and 500 pounds. Without springs, opening it manually would feel like lifting a truck. Springs store energy and release it gradually, making the whole operation smooth. They're also the hardest-working component on your door. Most springs last 7 to 9 years with regular use, but that timeline changes based on the type you own. See our guide on garage door opener replacement cost in daly city: what to budget.
Two main spring styles power garage doors: torsion springs and extension springs. Each has its own mechanics, lifespan, and price tag. Understanding the difference is your first step toward smarter maintenance decisions.
Torsion springs sit horizontally above your garage door, usually mounted on a rod that runs left to right. They twist and unwind to lift the door. Think of them like a clock spring that coils up and releases energy in a rotating motion. Most modern homes use torsion springs because they're more reliable and safer than their counterparts.

Here's what makes torsion springs stand out. They distribute force evenly across the door's width. That even distribution means fewer stress points and longer life. Torsion springs also fail more predictably. When one snaps, you'll usually hear a loud bang and the door stops working immediately. There's no guesswork involved.
One torsion spring can cost more upfront than an extension spring, but the payoff is worth it. A single torsion spring often handles the entire load on its own. Some doors have two springs for extra backup, but you don't always need both replaced at once. If you're curious about snapped springs and how to spot them, we've covered the warning signs in detail elsewhere.

Extension springs hang vertically on each side of your garage door opening. Instead of twisting, they stretch and contract like a regular spring. When you open the door, they extend. When you close it, they compress back to their resting position. Many older homes in the Bay Area still rely on extension springs.
Extension springs are cheaper initially. That's their main selling point. But they come with tradeoffs. Since you need two springs (one on each side) to balance the load, you're actually replacing twice as often. If one breaks, the other is usually close behind. Extension springs also wear unevenly because each side bears half the weight, and friction isn't always balanced perfectly.
Safety is another consideration. Extension springs use pulleys and cables. If a spring snaps, those cables can whip around and cause serious injury. Torsion springs fail more contained. For families with kids or pets, this matters.
Look inside your garage. Open the door halfway and stop it. Do you see a long metal rod running horizontally above the door with a spring wrapped around it? That's torsion. Do you see two springs hanging vertically, one on each side of the door frame? That's extension. Don't touch either one. Springs are under extreme tension and can cause severe injury if mishandled.

Torsion spring replacement typically runs higher than extension, but lasts longer. Extension springs might seem cheaper per unit, but you'll replace them more often. When you factor in labor, the total cost difference shrinks. Our detailed breakdown of garage door spring repair costs in Daly City covers pricing for both types.
Most professionals charge for the spring itself plus labor. Same-day service is possible in Daly City and surrounding areas like South San Francisco. If your door won't open and you need an estimate, call us right away.
Keeping your door balanced and lubricated can squeeze extra years out of your springs. Regular garage door maintenance prevents premature wear. Most homeowners skip this step and regret it when a spring snaps without warning.
If you're dealing with a snapped spring right now, don't force the door open. That's a common mistake that damages the opener. Our team handles emergency repairs seven days a week.
Your springs are the backbone of your garage door. Whether you have torsion or extension, they'll eventually need attention.

What is the difference between torsion and extension springs? Torsion springs twist horizontally above the door and typically last 7 to 9 years. Extension springs hang vertically and stretch to lift the door. Torsion is more durable and safer; extension is cheaper upfront but requires two springs.
How long do garage door springs last? Both types last 7 to 9 years under normal use. Frequency of opening and closing affects lifespan. A door opened 10 times daily wears springs faster than one opened 4 times daily. Regular lubrication extends life.
Can I replace just one spring? With torsion springs, you can often replace one. With extension springs, replacing just one is not recommended because the other is likely to fail soon after. Your technician can advise based on inspection.
How much does spring replacement cost in Daly City? Torsion spring replacement ranges from $250 to $400 including labor. Extension springs cost $150 to $250 per spring plus labor. Call 650-753-7227 for an exact quote tailored to your door.
Is it safe to DIY garage door spring replacement? No. Springs operate under extreme tension and can cause severe injury or death if they fail during installation. Always hire a licensed professional for spring work.
